摘　　要：将铝酸酯偶联剂和纳米ZnO同时用超声分散在熔融的己内酰胺中,一步原位聚合制备MC(单体铸塑)尼龙6/ZnO纳米复合材料,应用正交试验对偶联剂的用量和超声温度、时间等工艺参数进行了优化。结果表明,当超声温度为80℃、超声时间为20 min、偶联剂加入量为1.0%(质量分数)时,合成的MC尼龙6/ZnO纳米复合材料力学性能最优。通过SEM和XRD对MC尼龙6/ZnO纳米复合材料进一步的表征表明,ZnO在基体中达到了纳米级的分散,结晶形态理想。The nanocomposites of MC nylon6/ZnO were prepared by the direct in-situ polymerization with the coupling agent of aluminum alkoxide and nano ZnO disperseing together in the melt caprolactarn by ultrasonic. And the processing parameters, such as the adding amount of coupling agent, the temperature and time of the ultrasonic dispersing, were optimized by the orthogonal test. The results show that the properties of MC nylon6/ ZnO nanocornposites is best with the following optimized parameters： ultrasonic dispersing at 80 ℃ for 20 min, and adding 1%（mass fraction）of the coupling agent. Characterization of MC nylon6/ZnO nanocornposites by SEM and XRD show that ZnO is dispersed in the matrix as nano-sized particles and has an ideal crystallization morphology.
